Dynamical Tidal Response of Kerr Black Holes from Scattering Amplitudes
M. V. S. Saketh, Zihan Zhou, Mikhail M. Ivanov
We match scattering amplitudes in point particle effective field theory (EFT) and general relativity to extract low frequency dynamical tidal responses of rotating (Kerr) black hol…

Modeling horizon absorption in spinning binary black holes using effective worldline theory
M. V. S. Saketh, Jan Steinhoff, Justin Vines +1
The mass and spin of black holes (BHs) in binary systems may change due to the infall of gravitational-wave (GW) energy down the horizons. For spinning BHs, this effect enters at 2…
